CARL D. WIOKE, OF LEHE, GERMANY.

MACHINE FOR MANUFACTUFHNG TILES.

SPECIFICATION forming part of Letters-Patent No. 620,817, slated. March 7', 1899.

Application filed April 23, 1897.

To aZZ whom it may concern.-

Be it known that I, CARL H. D. WIOKE, a subject of the Emperor-of Germany, residing at Lehe, Hanover, Germany, have invented certain new and useful Improvements in Machines for Manufacturing Tiles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to machines for manufacturing cement tiles; and the object of the invention is to provide a press wherein the tiles are formed with strips and grooves, said press embodying in its organization a novel combination of devices, whereby the several operations of molding, compressing, and forming the tile are all accomplished successive to each other and the finished tile when ejected from the press is complete in every detail.

To this end the invention consists in th novel arrangement and combination of parts, as hereinafter described, and definitely set forth in the claims.

In the drawings, Figure 1 is a side elevation of the press. Fig. 2 is a top plan view of the press, showing the general arrangement. Fig. 3 is a detail-view of the pressing-roll and mold, showing the manner of rolling out a tile. Figs. 4, 5, 6, and 7 are cross-sections through the press, showing the parts in difierent positions. Fig. 8 is a top View of a tile. Fig. 9 is an under side view of the same. Fig. 10 is a cross-section through the same on a larger scale. Fig. 11 is a cross-section through the pressing-roll.

Like letters of reference indicate corresponding parts throughout the several views.

On the frame A of the machine a mold B is secured, which is provided in its interior with a plate B, on which rests a flexible lining of zinc O, which adapts itself to the form of the moldthat is to say, to the form of the inner or under side of the tile. A vertical shaft F, rigidly attached to the frame A, has revolubly mounted upon its upper end a rod E, serving as the axis of a conical roller D, which is loosely mounted on said rod. When not in use, the roller is carried by a rail G. Above the mold and pivoted in rear thereof is a supplementary or pattern frame H, which Serial No. 633,791. (No model.)

- when lowered can be secured to the mold by means of wedge-levers I, carried one on either side of said frame, which are adapted to be turned under the projecting edges of the mold B. Said frame is provided with guides J for the oblique slide K, carried thereby. A press-frame L, similarly pivoted to the frame A directly in rear of the frame H, is adapted to be lowered over' said frame, as hereinafter described. The press-frame L .carries angular lugs M, resting on eccentric fingersN, Fig. 6, which form prolongations of a lever 0, said lever being pivotally connected to a support P on the frame A. The lever O carries a projection R, resting after each movement of the lever on the lugs M. When not in use,the press-frame L and frame II are held in a slightly-inclined position by a support Q.

The machine operates as follows: The mold is filled with cement in a plastic state, and the conical roller D is revolved on its axis E and simultaneously turned around the vertical shaft F to pass over the mold, thus compressing the material, so as to force-it within the parts of the mold. (The roller D exerts a pressure of about two hundred and thirty pounds.) After this operation the patternframe H is lowered, Fig. 4, and secured to the mold by means of the Wedge-levers I, whereupon the oblique slide K is forced downward and by means of compression forms the groove 17 and gorge c of the tile, Figs. 8 and 10, and forms at the same time a compartment 0 for making the strips athat is to say, said compartment c is formed between the slide K in its present position and the edges of the mold-which corresponds exactly with the shape of the strips. This compartment is then filled with cement and the press-frame L is lowered upon the same, thus finishing the formation of strips a. The lever O is thereupon lowered, and the projections R of the same rest after such movement on the angular lugs M and give the necessary pressure for the compression of the part intended to form the strips a. Said lever O admits in the beginning of a gentle pressure of the press-frame L upon the soft cement mass, which is gradually increased for the final pressure on the whole tile. When the lever O is returned to its normal position, the fingers N come in contact with the lugs M, and thus raise the pressframe L.

To remove the ready tile from the mold, the following mechanism is employed: A pedallever V, fulcrumed in the lower part of frame A, has its arm S linked to a vertical shaft X by a curved strap U. A support W is mounted.

at the upper end of said shaft and has extending upwardly therefrom vertical standards '1, adapted to enter into corresponding recesses in the upper part of the press. When a tile has been completed,the lever O is thrown back, the press-frame L is lifted up, and also the frame If after having released the wedgelevers I, whereupon the tile can be removed. This is done by depressing the pedal V,whereby the standards T arev moved vertically through the press, thereby raising the tile from the mold. In other words, the said standards eject the tile, together with the flexible zinc lining aforementioned, as clearly shown in Fig. 7.

The form of tile manufactured in this machine is shown in Figs. 8, 9, and 10.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. In a machine for making tiles, the com bination of a mold-carrying frame, a mold supported thereon, a flexible lining provided in said mold, a compression-roller, a rail carrying said roller, a vertically-movable frame located above and pivoted to said mold-carrying frame, and carrying means for forming the tile, a vertically-movable press-frame in line with said vertically-movable frame adapt= ed to complete the compressing operation and suitable means for ejecting the finished tile, substantially as described. 1

2. In a machine for making tiles, the combination of a mold-carrying frame, a mold supported thereon, a flexible lining provided in said mold, a compression-ro1ler, a rail carrying said roller, a vertically-movable pattern-frame located above and pivoted to said mold-carrying frame, a slide movable in said pattern-frame, a press-frame pivoted to said mold-carrying frame in line with the patternframe, angular lugs carried on either side of said press-frame, a lever pivotally connected to said mold-carrying frame, said lever having prolongations forming fingers extending beyond its pivot, and adapted when depressed to compress said pivoted frame and press it upon the tile and when elevated to raise them by the reaction of said fingers, and suitable means for ejecting the finished tile, substantially as described.

V 3. In a machine for making tiles, the combination of a mold-carrying frame, a mold supported thereon, a flexible lining provided in said mold, a vertical shaft rigidly secured at one side of the frame, a rod pivoted at the upper end of said shaft and at right angles thereto, a conical roller revolubly mounted on said rod and adapted to traverse the top of said mold for compressing the cement mass therein, a rail to support said roller, a pattern-frame I-I pivotally connected to said mold-carrying frame, and having a slide K for producing grooves in the tile, said slide forming a compartment 0 to receive cement, a press-frame L similarly pivoted to the m0ld= carrying frame in rear of said pattern-frame for compressing the cement massin said compartment, angular lugs carried on either side of said press-frame, a lever pivotally con nected to said mold-carrying frame, said lever having prolongations forming fingers extending beyond its pivot, and adapted when de= pressed to compress said pivoted frame and press-frame upon the tile and when elevated to raise them by the reaction of said fingers, and suitable means for ejecting the finished tile, substantially as described.

In testimony whereof I affiX my signature in presenceof two witnesses.
